ENGR403 FIRE ENGINEERING CERTIFICATION
EVALUATION EXAM 2026 QUESTIONS AND
ANSWERS
◉What are the four mechanisms of heat transfer? Answer: 1.
Combustion
2. Flame spread
3. Fire propogation
4. Pyrolysis
◉What is thermal convection? And when does it occur? Answer: The
transfer of heat energy between solid materials and a fluid in motion.
Occurs during pre-flashover
◉What are the two methods of ignition? And how do they occur?
Answer: Polited ignition: There is a source of energy that triggers
ignition
Auto ignition: The temperature of the mixture is hot enough to provide
enough energy. This is harder to achieve
◉What are the characteristics of natural flow? Answer: The flow is
induced solely by the buoyancy of the flame
, ◉What are the characteristics of forced flow? Answer: The direction of
the flow is induced by ambient wind or a fan
◉What are the characteristics of opposed flow? Answer: The direction
of spread is in the opposite direction to the air flow
◉What are the characteristics of wind aided flow? Answer: The
direction of spread follows the direction of air flow
◉What is the typical threshold between a thermally thick or thin
material? Answer: 2 mm
◉What are characteristics of prescriptive code? Answer: Regulations
Lots of requirements
Recipe-like
◉What are characteristics of performance based code? Answer: Allows
for specific engineering design
Must fulfil the main objective of: life safety
◉Name five dimensions that affect someones perception of risk Answer:
1. Familiarity
2. Control
